How to I configure my E2000 router flashed with E2000 VPN, to assign a static IP to a new server? Correct me if I'm wrong but I think this also might be referred to as DHCP Reservation. I can find no instruction on how to do this anywhere. If there is a better forum to ask this question please inform me.

I can think of at least two ways, and there are probably more. 1) If you are fine with the IP the server currently has then go to Status > Device List. Find your server in the list and click "static". From then on every time the server asks for an IP that is the IP it will get. 2) Go to Basic > DHCP. Fill in the MAC and hostname of the server, plus the IP you want it to have. (I'm on Toastman's build where its under "Basic > DHCP/ARP/BW" but I think this function is part of build 54 under a different name, I can't remember)

I found that if I go to Status > Device List that my server is listed there. Then when I click on [static] right under the servers MAC address that it takes me to a similar menu that is under Basic > static DHCP (with the "static" before the DHCP) but I see no ARP or BW in that menu. I seem to have gotten it figured out. Thanks for posting.

But if anyone is willing to answer this; does DHCP Reservation mean just assigning a static IP?

I've got to learn more about IPs, I don't really have a good understanding of how they work in a local network.

You are likely using a quite old version of Tomato. Most of the newer versions from the various modders have several new features which you may find useful. However, the Basic/Static DHCP page is the one you want. Enter the MAC, and the IP you wish that machine to have, and you can also assign it a hostname which you will then see elsewhere when viewing statistics etc. Most people give a 1 day lease time to their clients, but that's up to you.

There are two ways to assign a "static" IP to a device. One is to set it manually in the PC itself. Or you can get the router to always assign the SAME IP to a particular device, which amounts to the same thing - that is what we are doing here. The router also tells the PC what DNS server to use (the router's) and the router's IP address (aka the gateway).

You may find it useful to always assign the same IP to all of your devices and give them a unique name in HOSTNAME. That way you will find it much easier to see who is using what on your system.

On newer versions, there are quite a few extra features that make the monitoring of your system easier. The ARP binding facility referred to is a security feature that has been added, and BW refers to the new IP Traffic Monitor which is in Toastman recent builds. Neither of those are in the build you are using.
